Part No. 7105
Caliper Bush Replacement Tool
Knorr-Bremse
Instructions
Reports from our customers suggests that the Knorr-Bremse brake caliper lower
sliders wear and seize over time which can lead to poor brake performance as well
as accelerated brake wear. This issue normally requires the complete removal of
the brake caliper from the axle.
Designed by an HGV Technician who brought his idea to Laser Tools, the Laser
7105 in most cases allows the lower slider to be replaced with the caliper on the
vehicle.
The tool kit is designed to work specifically with the caliper slider repair kits listed
(lower slider only).

Preparation
1. Using a suitable lever move the caliper on the sliders towards the centre of the
vehicle to ensure there is access to the inside face of the disc and the back face
of the caliper.
2. Remove the slider bolt cover to gain access to the socket headed caliper
mounting bolt. Check the bolt head is clean to ensure full insertion of the stubby
hex key provided (F).
3. Remove the lower caliper fixing bolt.
4. Clean the metal surface inside and out around the bush and slider.
5. Position the caliper to give best access to both sides of the bush and slider, if
possible raise the lower part of the caliper and use a wedge to hold the caliper
up.
NOTE: Before using this kit please ensure all threaded components are well
lubricated with Molybdenum Disulphide grease and free from grit and dust.
Failure to use the correct type of grease will void the product warranty.
Ensure before applying any load to the tooling that all components are
correctly aligned.
Extraction of Caliper Pin:
1. Lubricate the force screw (A) with Molybdenum Disulphide grease, Insert
through the centre of the caliper pin and fit extractor nut (D) on to the inner end
of (A). Ensure full contact between (A) and (D)
2. Assemble components H, B and J as shown. Holding the force screw (A) with a
suitable wrench wind the guide pin out using the force screw Nut and bearing
assembly as shown.
Fitting New Bush:
1. Remove any corrosion and dirt from the caliper slider bore hole and
surrounding area.
2. Lubricate the new bush using grease provided with the bush kit.
3. Slide the Support Guide (I) into the new bush and push the bush/Support
assembly in the Install Cup (E).
4. Lubricate the Force Screw. Assemble the Force Screw (A), Force Screw
Nut with bearing (J) with the Support Guide (I) and bush on to the caliper as
shown.
5. Screw the Pull-in Plate (C) on to the inner end of the Force Screw (A) ensuring
full thread contact.
NOTE: Ensure the raised ridge on the Pull-in Plate engages correctly with the
raised ridge inside the caliper to ensure the bush is correctly aligned.
OEM instructions state that the torque required to insert the bush should be
between 8<45 Nm. If torque required is outside of this limit the caliper should
be replaced.
6. Assemble the caliper as per manufacturer’s instructions, before fitting
pads ensure caliper slides freely and smoothly on the caliper sliders.
